I had then returned an HX Stomp over the last month. Actually some very solid sounds with it, especially with some good IRs. Being limited to 6 blocks just meant you had to be careful with your choices. Their Friedman model is phenomenal, and since the HBE/c45/saturation is all in the same model you can easily switch settings between snapshots. I had a whole range of sounds with just it configured.
Ultimately I moved away from it because:
- Footswitch configuration seems more flexible on Axe FX. Expression and external footswitches use a TRS-to-two-TS setup, which is a bit harder to find expression pedals for, and you couldn't assign the mode change (Stomp/Presets/Snapshots/etc) to one of the internal switches, just external.
- I wanted the larger range of amp models in the Axe FX, and some of the specific models that are only in the Axe (Mark IIC++!).
- Added flexibility of setup compared to the 6 block limit on the stomp
- More frequent updates
- I'm really far down the FM3 list, so by ordering the Axe FX III instead I had to do something to offset the cost
But there was definitely a part of me that thought about keeping it as a portable rig/holdover until I could get an FM3 invite, but I was still in the return window and getting a full refund was too tempting.
